To aZZ whom, it may concern: I

Be it known that we, Snnrrnoo RUBERT I and Pro RUBERT LeroR'rA, subf'ects of the tubes, or generators.

King of'Spain, residing at Baroe ona, Spain, have invented a certain new and useful Composition of Matter for Removing and Pre-,

venting lncrustation in Water-Receptacles, of which the following is a specification.

This invention relates to a composition of matter for removing and preventing incl-ustation in water-receptacles.

It is a welleknown fact that incrustation is produced in water-tanks, tubes, and the like, and more particularly on the inner surfaces of steam-generators, mainly owing to the presenceof calcareous and magnesian salts in the water introduced into the said tanks, It is also known that such incrustation has-great disadvantages and frequently constitutes, an element of danger in the working ofthe' apparatus in which it occurs.

The object of the prese'nt'invention is ,to

, provide a preparationfor admixture with .which, can be added to the water Water used for various industrialpurposes, the said preparation being not only adapted to remove existing incrustation, but also to prevent the formation of such incrustation y precipitating the calcareous or magnesian salts contained in the v ater in solution or in suspension. This pre aration, -before or durin use consists of acid sulfates, neutral phosp ates, and oxids of potassium and sodium, mixed in proportions which vary according to requirements and to the nature of the water used. A- neutral coloring substance can, if desired, be added to the preparation, and the latter can be used in a liquid, solid, pasty, granular, or pulverized state. If it is desired to use the mixture in a liquid state, the constituents thereof are dissolved inv water, whereas if the used in a solid state t e constituents are preferably first formed into .-a paste. with the aid of a suitable quantity of water, the said paste bein then, if desired, strongly compressed an molded or-cut into cakes of suitablesize. The paste can, if desired, be introduced into jars or -other storage-recepta else before itdries, or it can be dried and pulverized or reduced to a granular state. The preparation can also be produced by inti mately mixin suitable proportions of the CODStitllBlltSWl116 dry.

What we claim as our invention, and desiretosecure by Letters Patent of the United States,

1. A com osition of matter for the purpose set forth consisting of a mixture of acid preparation is .to be,

sulfates,-neutral phosphates and oxids of In witness whereof we have signed this I specification in the presence of two Witnesses.
